FLOATING WING FOR EXCAVATING IMPLEMENTS Filed July 15, 1943 2 Sheets-Sheet 2 PatentedSept. 12 1944 UNITED STATES PATENT OFFICE j FLOATING WING FDR. EXCAVATIN G IMPLEMENTS This invention relates to a floating wing for an excavating implement and has relation more particularly to a wing for use in connection with an implement used in the ,oil fields in taking up pipe lines. I

It is a particular object of the invention to provide a Wing which can be readily applied to or mounted upon an implement in a manner permitting variation in depth of plowing without alteration of the wing position.

It is also an object of the invention to provide a floating wing which, when in applied position, is free to move to ride'upon the top of the ground surface to provide means to push the dirt raised by the implement away from the ditch.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved floating wing for an excavating impIement Whereby certain important advantages are attained, as will be hereinafter more fully set forth. 7

In order that myv invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein: I

'Figure 1 is a view in side elevation of a floating wing constructed in accordance with'an embodiment of the invention and in appliedposition.

Figure 2 is an enlarged view partly in section and partly in elevation of the floating wing as herein comprised.

Figure 3 is a view in top plan of the floating 'wing with portions broken away.

This plow I depends from the rear end portion of a beam 3, the forward end portion of which is connected, as at 4, to the forward extremity of an elongated bolster 5.

3 Claims. (Cl. 3798) jacent rear end portion of the bolster 5 to provide means whereby the beam 3, together with the plow I and the member 2, may be'raised as desired or allowed to drop.

The forward extremity of the plow beam 2 has associated therewith a suitablehi'tch 9 while the lower end portions of the vertically disposed ities of which are mounted the ground-engaging wheels I I. The plow I is positioned rearwardly of v the axle or shaft l0 and the ground-engaging wheels II' are arranged at amaterial distance outwardly of the beams 6. The particular construction of the implement E, as herein disclosed, in itself forms no'part of the present in- I vention as it is of a type. now well known in the oil fields. g 1

The beams 6 in their upper portions and at points herein disclosed as closelyadjacent to the under surface of the beam 3 are cash provided with the rearwardly disposed lug I2 with which is pivotally engaged a link I4 also pivotally connected to the forward extremity of one of the upwardly inclined parallel elongated members I 5 The rear or lower end portions of these members I5 extend through and are rigidly secured to the rear transverse member I6 of a substantially V5 shaped frame F,-'the apex portion of which is forwardly disposed.

length thereof are the substantially verticall dis- To the forwardly converging side members I! of the frame F are secured the mold boards I8 of desired dimensions and which have their forward converging extremities spaced apart a material distance or a mean distance approximating the width of the ditch being dug by the plow 'I. These mold boards I8 are preferably arranged on an angle of about 30 degrees and are rigidly maintained in desired assembly by the interposed frame F to which said mold boards are attached.

When the floating wing structure is applied, the mold boards I8 freely ride on the ground surface to th rear of but closely adjacent to the plow I and extend outwardly and rearwardlyfrom the line of travel, so that a the implement advances, the dirt raised up by the plow twill be pushed away from. the ditch to prevent the dirt falling back onto the pipe line before it can be raised. l

The central portion of the rear member I S of the frame F is provided with an upstanding eye member I9 to which is secured. the lower extremity of a flexible member'ZII, herein disclosed as a chain. This member or chain I9 threads through an outstanding eye member 2| carried'by the rear end of the beam3 and said no particular importance.

member or chain 20 at its outer extremity .is herein disclosed as carrying a hook member 22 which may be readily selectively engaged with the member or chain 20, whereby effective means is provided to support the rear portion of the floating wing attachment and more particularly when said wing attachment is to be maintained in a raised position whenthe implement is not in use or is being transported from one location or operation to another.

When the plow I is being'used for deep digging or excavating, it is advisable to employ the rear additional or supplemental'mold boards 23. These mold boards 23 do not have to be of the same width as the forward or permanent mold boards [8 as the width of such boards is of edges of thesemold boards 23 should be substantially coplanar with the lower margins of the boards l8. These mold boards 23 are disposed on forward convergence on a desired angle and the forward extremities thereof are detachably connected in any desired manner with the short However, the lower' depending arms 24at the sides of the'jframe F at the rear thereof, and therear or outer ex tremities of these supplemental mold boards 23 are connected by the interposed bracingand re- 'It is believed to be obvious from the foregoing that .in practice the mounting of the floating 'forcingmembers 26. 7

What is claimed is: 1. An attachment for a ditching machine includi'ng a frame and a plow carried thereby, comprising a horizontally disposed frame having converging sides, a pair of mold boards each secured to one of said sides of the second mentioned frame, said mold boards being maintained by the said convergent sides of the second mentioned frame in forwardly converging relation,

the convergent ends of the mold boards being spaced apart adistancesubstantially equal to the width of the .plow, apair of draft beams secured to the second mentioned frame between the mold boards and extending forwardly and upwardly, and means for pivotally coupling the said beams at their upper ends to the ditching plow frame in a position where the'forward'ends of the mold boards are at the sides of the plow and immediately to the rear thereof.

2. An attachment for a ditching plow having a main frame and a plow member carried there- 7 by, comprising a horizontal frame having a horizontal substantially V shaped forward portion and a rear portion in the form ofa transverse beam, said horizontal frame having forwardly converging sides, a pair of mold boards each secured to a side of the horizontal frame and maintained thereby in forwardly convergent re-i lation with the opposite mold board, a pair of draft beams each extending through and secured ,to the transverse beamof the horizontal frame 7 and extending forwardly and upwardly across the top of the V portion of said horizontal frame at a, forward and upward inclination, said draft beams being designed for connection with the frame whereby the attachment may have Vertical movement relative to the first frame.

3. VA ditching plow attachment as set forth, a

in claim 2, in which thetransverse beam of the horizontal frame has downwardly extending end portions forming arms to which saidmold boards are secured, and coupling links between the mold boards and the draft beams, forwardly of the horizontal frame.
